I have a situation where i have 3 ObjectDataProviders the first two works, the game ObjectDataProvider (ODP) populates the cboAllGames ComboBox, when game is selected, then the GameYears uses Id from selected game, it's ODP receives the selected gameid and populate the comboBox successfully. Now the third one i can't figure out how to grab the selected game id from the cboAllGames ComboBox SelectedValue, and the selected years from the cboGameYears ComboBox Selectedvalue? So the ObjectDataProvider can retrieve data from the Object to populate the DatGrid?
